RAZOR-BLADE HULDER.

Application filed lvfay To all whom it may concern Be it known that I,don J; SCHULTZ, a citi zen of the United States, residing at l Vindsor,in the county ofStutsman and State of North Dakota, have inventedcertain new i and useful Improvements in Razor-Blade .Holders, of whichthe following is a specification, reference being had to theaccompanying drawings. y i I i i This invention relates tolIIlPlOVBllflBlltS- 1n razor blade holders, and more particularly toadevice for holding razor blades while sharpening the same.

Anlimportaht object of. the invention is a to provide a devioe'of thischaracter which maybe either separately constructed or constructed uponthe tangof a razorblade or of alrazor blade holder constructed inimitation of the usual straight style of razor.

A further object of the invention is to provide a device of thischaracter to which. a blade may be readilyfapplied and by which theblade when applied is held firmly in position.

may be very cheaply and readily constructed. These and other objects Iaccomplish by theconstruction and arrangement shown in the accompanyingdrawings wherein for the purpose of illustration is shown a preferredembodiment of my invention and wherein a like reference charactersdesignate like parts in F igure 1, the shank comprising the tail orfinger receiving portion of a razor blade or blade holder.

Referring now more particularly to the drawings, the numeral. 10indicates a handle portion, whichmay, as hereinbefore stated, be formedeither of a separate piece of material or by the blade portion of arazor or the blade holding portion of a safety razor constructed inimitation of the ordinary razor construction, the first and last con-VVhere an.

structions being herein shown. ordinary handle is employed, it isprovided with a reduced blade holding extension 11 A still furtherobject of the invention is to provide a device of this character whichSerial No. 558 88 3.

forming at the end of the handle a shoulder 12 provided with an undercutslot 13 flush with the upper surface of the blade holding extension 1.1,the purpose of which will hereinafter appear.

At the end of the blade holding extension 1]. an offset 14: is providedat one side of the blade corresponding to the thickness of av safetyrazor blade 15, the extension. being of a width equal to the internalslot 16 formed in certain types of safety razor blades. The upper end ofthe offset le is provided with an enlarged head 17 of greater width thanthe slot 16 of the blade to be employed. The combined. thicknesses ofthe extension 11, offset 1.4 and head 17 are less than the width of theslot 10 so that by turning the blade transversely of the slot the sameinay be applied over the head. By then arranging the bladelongitudinally of the extension 11 the blade may have its end moveddownwardly into engagement with the uppersurface of the extension ll.and aligned with theslot 13y so that it may enter therein. As is wellknown to those familiar with the art, the slots 16 of this type of razorblades terminate short of the ends thereof and accordingly acomparatively broad, flat surface is formed which bears against theupper surface of the arm. This bearing, when the blade is infully'applied position and engaged in the undercut slot, effectuallyprevents downward movement of the outer end of the blade since i themetal between the end of the slot and the end of the blade will bearagainst the upper surface, and the end of the blade is effectuallyprevented from elevation by the overhanging shoulder formed by the slot.Movement in the opposite direction will, of course, be prevented by thehead 17 and transverse movement of the blade will be prevented by theengagement of the ofi'set 14 against the side walls of the slot 16.

l Vhen it is desired. to form a blade holding device in accordance withmy invention upon the shank of a razor or blade holder constructed inresemblance of a razor, the

terminal portion 18, which is adapted to be engaged by the fingers whileshaving, is formed to provide the structure hereinbefore set forth, asindicated in Figure 8.

From the foregoing it is believed to be obvious that a blade holderconstructed in accordance with my invention is particularly well adaptedfor the purpose for which it is intended by reason of the fact that theblade may be readily applied to and removed therefrom and will be veryfirmly held when applied. It will furthermore be obvious that theconstruction as hereinbefore set forth and illustrated is capable oisome change and modification without materially departing from thespirit or my invention and I accordingly do not limit myself theretoexcept as hereinafter claimed.

I claim 1. The combination with a longitudinally internally slottedrazor blade, of a member having .a shank provided with an extension,said extension being of a width substantially equal to the slot of theblade and provided at one side thereof with a head of greater width thanthe extension, and a slot formed in the shank of the member and adaptedto receive the end of a blade engaging said extension and having thehead thereof extending through the slot.

2. The combination with a razor blade having an internal longitudinalslot, the ends of which are spaced from the ends of the blade, of amember having a shank provided with an extension of a widthsubstantially equal to the slot of the blade and pro vided at one sidethereof with a head of greater width than the slot of said blade and aslot formed in the shank of the inemher and adapted to receive the endof a blade engaging such extension and having the head thereof extendingthrough said ccnt end of the slot of the sl: ank a distance slightlygreater than the distance between the ends of the slot and the ends ofthe blade.

3. The combination with an internally longitudinally slotted razorblade, of :1 memher having a shank provided with an extension, saidextension being of a width equal to the width of the blade and providedat one side thereof with a relatively wide head offset from theextension a distance approximately equal to the thickness of the bladesaid member having a slot formed in the shank thereof openin towaixlsaid head and adapted for the reception of the end of the blade whenengaged with said extension and having the head of the extensionextended through the slot thereof.

4. A razor blade holder for blades having an internal longitudinal slotcomprising a shank having an extension against which a portion oi thebody of the blade is adapted to rest, the extremity of the extensionbeing provided with a relatively wide head adapted for extension throughthe slot, and the shank being provided with an overhanging portiondisposed at the same side of the extension as the head and adapted tooverlie the end of the blade.

In testimony whereof I hereunto ailix my si nature.
